IMPROVEMENT IN BLOWING APPARATUS FOR ORGANS.

Specification forming part of Letters Patent No. 121,269, dated November 28, 1871.

To all whom it may concern:

Be it known that I, JOHN F. BARKER, of Springfield, in the county of Hampden and State of Massachusetts, have invented a new'and useful Improved Organ-Blowing Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing making a part of this specification, and to the letters of reference marked thereon, in which- Figure 1 is a vertical section of my invention through its center, and Fig. 2 is a similar view of another modification of the same.

My invention relates to an apparatus for forcing a constant current of air into the wind-chest or reservoir of church-organs; and it consists of an open vessel inverted within another vessel, the closed end of the first having an orifice therein opening into a pipe secured thereto, the upper end of said pipe having another smaller pipe secured therein, in the lower end of which is a small orifice, the other end of said pipe being connected to a hydrant or other convenient water supply. The larger pipe is perforated a short distance below the upper extremity, and the vessel to which said pipe is attached at the lower end has another opening communicatingthrough a pipe with the interior of the wind-chest or the reservoir of an organ. The inverted vessel is retained in its position by means of stays secured to both vessels, and a third vessel is secured in the bottom of the larger and outer one; and in order that the fiow of air into the windchest or reservoir may be as steady and uninterrupted as possible, a regulator, having a dia phragm, is provided; or the smaller vessel to which the pipes are attached is made so that it may rise and fall, according to the pressure of the air Within, a yoke being provided attached to the outer vessel extending from one side to the other over the movable vessel, the pipe which is attached to the latter passing up through said yoke, and a rod attached thereto or to the diaphragm operating to open or close the valve or Water-cock.

That others skilled in the art may be able to make and use my invention, I will proceed to describe its construction and operation.

In the drawing, B represents a vessel of any convenient size, open at the top, and having secured therein another vessel, D. Another vessel, of a suitable size to pass in between the vessels B and D, is inverted within the vessel B, and at the upper and closed end is attached the pipe E, which may be of any convenient length, and the upper end of this pipe is closed by another smaller pipe, F, the lower end of which projects a little into the pipe E and has a small orifice, f, in the end; and the device operates more satisfactorily if this orifice f is made longer in one direction than in the other, so that the stream of water which passes through shall be somewhat broad and flat; the pipe E is also provided with orifices a a near the point where the pipe F terminates. In Fig. 2 the vessel A is shown as secured in place by means of stays (l secured to the vessels A and B. H represents the wind-chest or wind-reservoir of the organ, and c the pipe leading from the orifice c in the vessel A to the wind-chest.

The operation of the device is as follows: If the pipe F, which may be as long as desirable, is connected to a hydrant or, other convenient water supply, the Water, upon opening the valve, passes down the pipe F and through the small orifice f and pipe E into the vessel D. The orificefbeing so much smaller than the diameter of the pipe F, the Water passes down through the pipe E with considerable velocity, and this creates a current of air passing into the pipe E through the orifices a a, which current passes down the pipe with the water. As the water fills the vessel D it overflows into the vessel B and rises therein above the open lower 'end of the vessel A. When this occurs the vessel A is sealed and the air which is brought down the pipe E into said vessel cannot escape except as it passes out through the orifice c and pipe 0 into the wind-chest H, and this current of air will continue to flow through the pipe E, vessel A, and pipe 0, and into the wind-chest or reservoir as long as the water continues to flow through the pipe F and orifice f. Of course, if the vessel A, with the pipes E and F, are made sufficiently large and the force or head of the Water is sufiicient to give a stream of Water through the pipe E of a velocity proportionate to the size of the apparatus, a current of air may be obtained of great power, and this power may be husbanded so that much or little of it may be used at times, according as more or less of the organ is used. This may be accomplished in the following manner: In Fig. 1, 0 represents a yoke secured to the sides of the vessel B and extending from one side to the other over the vessel A. An aperture is made in the yoke, through which the pipe E extends. The vessel A is thus free to move up or down, and as the air accumulates in the vessel A it will cause the said vessel to rise if but little of the air is being used. When more air is required to fill the chest as more of the organ is used, the vessel A, being of sufficient weight, will fall, forcing more of the accumulated air through the pipe 0 and into the wind-chest. Of course the pipe F should be sufficiently long, and properly jointed and connected, to allow the vessel A to have this vertical movement. It might be connected to the water-supply by a flexible pipe in order to get this movement. If desirable, an arm or a rod may be attached to the pipe E or to a pin, a, thereon, and said rod be connected to the valve which controls the flow of .water through the pipe F, so that when the vessel A and pipe E should rise to a certain height the rod would operate to partially close the valve, and to open it again as the vessel descends. If, however, it should be deemed preferable to have the vessel A firm, a vessel, 1, may be used, as shown in Fig. 2, attached to the pipe 0, and having a diaphragm, d, therein, which is sufficiently flexible. This diaphragm has a rod or weight, 6, attached, extending up through the top of the vessel, so that the excess of air forced into the vessel A, in Fig. 2, will pass through the pipe 0 and orifice 1) into the vessel I beneath the diaphragm d. This will cause the diaphragm to extend or rise, forcing up the weight 6, which may be sufficiently heavy to press down the diaphragm, forcing out the air beneath into the wind-chest H or reservoir, when more of the organ is used or more wind required. A rod may be attached to the weight 0, or the weight itself, extended, may serve to open or close the valve, admitting the Water as in the other case. Steam may be used with this device if desirable, to force in the wa ter with any desired degree of power or force through the aperture f, by simply attaching to the pipe F the device commonly known as the Git'fard injector, as it is simple in its construction, and will drive the water through the orifiee f with any desired degree of force. The vessel B may be set in a pit or race-way to a sewer, and the waste water run off over the top of the vessel B; or an outlet, N, be made in the side of said vessel, and a pipe attached to carry ofi the waste water. The apparatus will be quite satisfactory in its operation if the inner vessel or chamber D be omitted, or if it be covered or made in any other desirable form, as its use is designed to prevent the air, as it first enters the vessel, from being mixed too much with the water and carried out over the top of the vessel B, as might be the case if the chamber or vessel D were not used.

This apparatus is effective, is cheap, cannot be easily deranged, and will give an ample supply of wind as long as the water will continue to run, and needs no attention whatever while in operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The pipes F and E, the vessel A whether made movable or fixed, and the vessel B either with or without the chamber D therein, in combination with the wind-chest or reservoir of an organ, substantially as and for the purposes described.

2. The pipes F and E and the vessels A and B, either with or without the chamber D therein, in combination with the wind-chest or reservoir of an organ, substantially as and for the purpose described.
